Abstract
There has been much work on identification and inference with instrumental variables in the last decade. Researchers have investigated conditions for identification of causal effects without normality, linearity, and additivity assumptions. In this discussion, I will comment on some of the new results in this area and discuss some implications for applied researchers in the context of some specific examples, focussing on identification rather than inference. Most of the comments will be limited to the case with a binary endogenous
